Why Isn’t My Furnace Working?
If your heater isn’t working, you might be wondering why. The truth is that there are several possible reasons your heating system is acting abnormally and not performing as strongly as it used to. Furnaces, heaters, and heat pumps are complex systems that require regular maintenance to keep all their components fully functional. Yet even with proper maintenance habits, a heater’s parts could potentially fail, causing the whole system to stop working properly.
Common heating issues we repair include:
- The heater is blowing cold air
- The furnace’s pilot light won’t stay lit
- The heater won’t shut off
- The system is failing to heat certain rooms
- The furnace controls are not working
- The heater fan does not work
- The furnace has moisture and mold buildup
- The heating system is short cycling
- The heater smells like its burning
All the issues above can be the result of a more serious problem in your system. For example, you might have a dirty air filter, a malfunctioning blower, a faulty thermostat, a broken motor, inadequate ductwork, or even a lack of fuel. Whatever the specific problem, our San Antonio heating repair technicians have the training and knowledge to get to the bottom of it immediately. Once we make an accurate diagnosis, we can walk you through your best repair options. We’ll then get to work to remedy the issue as quickly and effectively as possible.
The Danger of DIY Repairs
At Zimmermann Air Conditioning & Heating, our San Antonio heater repair experts completely understand that doing things yourself around your home is a great way to save money. However, when it comes to a complex mechanical system, like a furnace, specialized knowledge is required to perform repairs. More often than not, when a homeowner attempts to fix a heating system on their own, it ends up costing them more money in the long run. Many of our customers could have saved lots of cash and avoided replacing their system so soon had they relied on our professionals from the get-go.
